Gas compression control system modification project on an FPSO, United Kingdom

September 2021

From a compressor control optimalization study performed in 2019 by Control-Care, to project execution phase in 2021 for an FPSO located in the United Kingdom. Involved in this study and execution phase were two variable speed centrifugal compressors used for oil gas separation installed on board.  Essential control system modifications were made to the 25+ year old control philosophy and PLC system for both compressors to improve operability of the units, increase production and to reduce downtime of the units due to unexpected process trips.  The new control strategy was flawlessly implemented offshore following a thorough (remote) FAT using the end user’s spare controllers with end user’s PLC software staged in Control-Care’s premises.  

Remote support solution using augmented reality (AR) assistance tool, the Philippines

August 2021

Control-Care has successfully provided augmented reality (AR) remote assistance services for calibration, troubleshooting and testing of the main steam control valves on two 150MW steam turbine generator (STG) units for AboitizPower subsidiary Therma South, Inc. in Davao, Philippines. Due to covid travel restrictions our engineers could not be present on site. This remote assistance solution has enabled the end-user to still carry out the required activities effectively and accurately, without jeopardizing the turn-around schedule. The end-user’s engineer was carrying the AR remote assistance tool, whilst the Control-Care expert was monitoring and providing instructions from the headquarters in The Netherlands. The AR remote assistance tool is suitable for harsh industrial environments and ensures a safe working environment since it enables the user to still operate “hands-free”.
